The court in this Act is the only court that can hear a charge against a person who it is claimed committed an offence when he or she was a juvenile. The court must deal with this person in keeping with this Act only.

Diversion measures or court proceedings may continue even after the juvenile attains the age of eighteen. If it is proven during the court proceedings that the offence was committed after the person turned 18 years old, that person shall be sentenced as an adult.
